Description

【０００１】
【発明の属する技術分野】
本発明は、頭部が折り込まれた角部と、その上に折り重ねた中央部とを有し、この中央部に２つの自由な端部を有する糸が固定され、この糸を頭部の一方の側から穴に通して頭部の他方の側に配置された輪を作って引き戻し、両方の自由な端部が下方から煎じ出し袋の頭部縁の上に置かれた輪に通し入れて引っ張ることにより結び目を形成する、特に茶のための煎じ出し袋に関する。さらに本発明は、折り込まれた角部と、その後で折り重ねた中央部とによって頭部が閉じられた、特に茶のための煎じ出し袋を、２本の針を用いて、好ましくは他方の端部にラベルを付けた糸によって閉じる方法に関する。
【０００２】
【従来の技術】
煎じ出し袋を、もっぱら１本の糸で閉じることが知られている。このために煎じ出し袋の頭部で最初に角部を折り込み、次いでこれらの折り込まれた角部の上に中央部を折り重ねて煎じ出し袋を確実に閉じる。この閉鎖は１本の糸によって確保されているが、糸の取り付け方には幾つかの可能性がある。
【０００３】
ドイツ実用新案登録第２９６１３４４８号に記載された公知の技術では、煎じ出し袋の頭部に置かれた糸を別の固定糸を使って縫い付ける。この方法で糸端部を煎じ出し袋と結合すると、比較的高い荷重に耐えられず、技術上においてもコスト高となる。
【０００４】
より簡単な糸結合を提供するために、欧州特許第０８０７５７９号において、折り込まれた頭部に２つの穴を設け、煎じ出し袋を緊張した糸の横に配置し、この糸が穴の高さに延びていて、糸を受容しその両端部を穴に通す把捉針が各々の穴を貫通できるようになっている。煎じ出し袋の穴を貫通する糸の自由な端部をラベルに、たとえば溶接又は縫い付けにより固定する。この場合の短所は、固定がゆるく、したがって不安定であり、頭部の折り重ねた領域が開く可能性があり、その結果、煎じ出し袋の内容物が脱落したり、香りや新鮮さが失われたりする恐れがあることである。
【０００５】
さらに欧州特許第０６９１２６８号に開示されたる糸閉鎖では、針が煎じ出し袋の頭部の唯一の穴を貫通し、この針がその後ろに位置している糸を把捉し、穴を通って輪を形成して戻り、次いでこの輪を結び目の形成に使用する。この場合の短所は、頭部の折り込まれた角部とその上に折り重ねた中央部とが互いに、及びまた袋と糸結合によって把捉され、形成された結び目によって結合されることが確保されていないことである。この場合は、たとえ高い製造精度で、折りたたみ、穿孔及び糸案内を行っても閉鎖は十分確実ではない。
【０００６】
【発明が解決しようとする課題】
本発明の課題は、煎じ出し袋の折り重ねた部分を互いに、及びまた袋と確実に固定することを、技術的コストが少なく、高い製造速度で簡単に作れる糸結合によって確保することである。
【０００７】
【課題を解決するための手段】
この課題を解決するために本発明では、頭部で袋の長手方向軸心の左右に互いに側方間隔を置いて配置された２つの穴が形成されており、これらの穴がそれぞれ頭部の折り込まれた角部と中央部とを貫通していて、糸の一方の端部を第１の穴に通し、他方の端部を第２の穴を通して輪を形成し、この輪が煎じ出し袋の頭部縁上に置かれていて、糸の両端部を下方から輪に通し入れて二重に固定された結び目を形成するようにした。この場合、好ましくは輪が交差して上下に重ねた糸部分によって形成されていて、短い糸端と長い糸端とを設けることができる。特に長い糸端はラベルを固定するために用いる。好ましい実施形態では結び目の安定性を高めるために、短い糸端が輪の交差して上下に重ねた糸部分において長い糸端の下方で袋壁に接して配置されている。本発明により、折り曲げた角部とその上に折り重ねた中央部とを互いに、及びまた袋と確実に固定することができる。この場合、慣用的な袋が比較的厚く、したがって加工しにくい長手方向シームを突き抜けたり、穿孔したりする必要がないということによっても単純化された製造が提供される。結び目による結合それ自体は、間隔を置いた２つの穴を設け糸端をそれぞれ別個に通すことによって二重に解けないようになっている。そのため、万一一方の糸端が輪から解けた場合でも、結び目は第２の糸端によって形成された追加的な巻き付けにより確実に保たれる。
【０００８】
冒頭に記載した公知の方法を改善することにより、本発明の方法に関する解決手段は、糸の自由な端部を保持具の凹部をまたぐ輪にして、煎じ出し袋の頭部を保持具内に導入して、その際に糸の輪を煎じ出し袋の頭部縁の回りに置くようにし、次いで糸の自由な端部と連続する長い部分とを折り重ねた部分を貫通する頭部の２つの穴に通し、自由な端部と連続する部分を最初に輪に通して、次いで煎じ出し袋から完全に引き出して、最後に連続する部分を引っ張って糸の巻き付けを引き締めることを特徴とする。好ましくは糸を把捉するために、輪の閉じた部分の下方で煎じ出し袋を貫通する２本の針を使用し、しかも保持具はこれらの針に対する案内開口部を有することができる。糸を引き通すために、遅くとも針を引き戻す前に糸を連続する部分で切断しなければならない。このようにして連続する部分は長い糸端を形成し、ラベル固定に利用できる。
【０００９】
本発明による方法は、煎じ出し袋の折り込まれた頭部を１本の糸だけで閉じ、補助糸は使用しない。糸は針によって煎じ出し袋の頭部を貫かれ、又は突き通される。この場合、保持具が針に対する案内開口部を有している。これらの針は煎じ出し袋の頭部を突き刺すために単純な運動を行うだけなので、単純で迅速な運動経過が可能である。またあらかじめ煎じ出し袋の頭部に穴をあけておく必要はない。袋頭部は中央の左右に糸を突き通すことによって確実に閉じられ、折り曲げられた角部も固定される。連続的に作動する方法により、固定は静粛な機械運転において高い個数で実施できる。結び目は、わずかな元応力のもとでも、すなわちゆるく引き締めたとしても、摩擦力に基づいて解けることはない。
【００１０】
【発明の実施の形態】
以下に、本発明の実施例を図面に基づいて詳しく説明する。
図１の（ａ）〜（ｃ）に示した煎じ出し袋１は、図１（ｃ）に従い最初に頭部６で角部１ａ及び１ｂを折りたたみ、次いでその上に中央部１ｃを折り重ねて閉じる。そうすると室の内部に存在する物質、特に茶が外に出ることはない。次に図２（ａ）〜図９（ｂ）に示すように、煎じ出し袋１に糸閉鎖７を設ける。その構造は特に図１（ｂ）で良く分かる。糸閉鎖７を形成するために、頭部６に袋の長手方向軸心の左右に互いに側方間隔を置いて配置された２つの穴８、９が形成されており、それぞれ頭部６の折り込まれた角部１ａもしくは１ｂと中央部１ｃとを貫通している。これを可能にするために、図１（ｃ）に示すように、まだ中央部１ｃを折り重ねていない状態で、煎じ出し袋１の頭部６に計４個の穴が設けられている。これらの穴は中央部１ｃを折り重ねた後では、互いに合致して同軸的に貫通する穴８及び９を形成する。
【００１１】
さらに糸閉鎖７は糸３を有している。糸３は輪３ａを作るように一方の端部３ｂが第１の穴９を通され、他方の端部３ｃが第２の穴８を通される。輪３ａは図面では袋１の前側にあり、角部３ｂ及び３ｃは図面では袋１の後側にある。輪は煎じ出し袋１の頭部縁１０上に置かれていて、糸３の両端部３ｂ及び３ｃは下方から輪３ａを通されている。糸の一方又は両方の端部を引くと、二重に固定された結び目１１が形成される。この結び目１１は、角部１ａ及び１ｂと頭部６の中央部１ｃを閉鎖位置で互いに、及びまた煎じ出し縁と固定する。
【００１２】
さらに図面に見られるように、輪３ａが交差して上下に重ねた糸部分によって形成されており、短い糸端３ｂは、輪の交差して上下に重ねた糸部分において長い糸端３ｃの下方で袋壁に接して配置されている。
【００１３】
上記の閉鎖を形成するために、図２（ａ）及び（ｂ）に示すように、煎じ出し袋１は閉じられた頭部６が、保持具２の凹部２ａに挿入される。それ以前に輪３ａの形をした糸３が保持具２の凹部２ａをまたいで通されているが、これは図２（ｂ）で最もよく分かる。この場合、輪３ａの自由な端部３ｂは糸３の連続する部分３ｃと共に凹部２ａの一方の側に載り、輪３ａの閉じた部分は保持具２の凹部２ａの他の側に載っている。
【００１４】
図２（ａ）から最もよく分かるように、輪３ａは煎じ出し袋１の頭部縁により凹部２ａ内に押し込まれるので頭部縁の回りに置かれる。
図３（ａ）及び（ｂ）に示すように、図２の（ａ）及び（ｂ）では出発位置で示されている２本の針４が、輪３ａの下方で煎じ出し袋の頭部を突き通す。これらの針４は、図３（ａ）及び（ｂ）に示されているように、下側に形成された鉤部４ａ（図２（ａ）参照）で、一方では糸３の自由な端部３ｂを掴み、他方では糸３の連続する部分３ｃを掴む。
【００１５】
ここで図４（ａ）及び（ｂ）に従い針４が出発位置に引き戻されると、これらの針４は、図４（ａ）及び（ｂ）に示すように、一方では糸３の自由な端部３ｂを連行し、他方では糸３の連続する部分３ｃを連行する。自由な端部３ｂが煎じ出し袋１の頭部から完全に引き出される一方で、対応する針４を引き戻すことにより糸の連続する部分３ｃに、輪３ａの中央部の下方に位置する輪３ｄが形成される。この状態は図４（ｂ）に明瞭に示されている。
【００１６】
さて、図５（ａ）及び（ｂ）に示された、糸３の端部による煎じ出し袋１の頭部の完全な巻き付けを達成するためには、連続する部分３ｃ、すなわち糸３の長い糸端部を煎じ出し袋１から完全に引き出すことが必要である。これは、たとえば煎じ出し袋１の継続搬送によって行われ、糸３の連続する部分３ｃの残りの部分が完全に輪３ａを通される。最後に糸３の連続する部分３ｃに規定の引張力を加えることにより、巻き付けを引き締めて、図５（ａ）及び（ｂ）に示す状態が生じる。
【００１７】
図６（ａ）〜図９（ｂ）に示されているラベル５を糸３の他方の端部に固定するために、図６（ａ）及び（ｂ）に示すように、糸３の端部３ｅをラベル５の一方の側に置く。好ましくは、またもや鉤部を付けた針を用いて、ラベル５を突き通し、糸３の端部３ｅを把捉する。図７（ａ）及び（ｂ）に示すように、端部３ｅは輪３ｆの形をしてラベル５を引き通される。
【００１８】
このとき輪３ｆが把捉され、図８（ａ）及び（ｂ）に示すように、ラベルの縁領域に形成されたスリット５ａ内に挿入される。このようにすることによって輪３ｆの閉じた部分は、再び糸３の端部３ｅ及び連続する部分が存在するのと同じラベル５の側に位置する。この状態は、図９（ａ）にて最も明瞭に説明されている。
【００１９】
最後に、糸３に引張力を加えることにより、ラベル５の回りで巻き付けが引き締められ、図９（ｂ）に示す状態が生じる。
煎じ出し袋１の閉鎖及び糸３の両端部へのラベル５の固定に関する上記の説明から明らかなように、いずれの場合も単純な手段で煎じ出し袋１もしくはラベル５の巻付けを達成できる。この場合、糸３の付着は、煎じ出し袋１の信頼できる閉鎖もしくはラベル５の信頼できる固定を達成するのに十分である。
【００２０】
【発明の効果】
本発明により、１本の糸で煎じ出し袋を閉じるための単純な技術的装置と高い作業速度で作動する方法が提供される。

BACKGROUND OF THE INVENTION
The present invention has a corner portion into which the head is folded and a center portion folded on the corner portion, and a thread having two free ends is fixed to the center portion. Make a ring placed on the other side of the head through the hole from one side and pull it back, both free ends from the bottom through the ring placed on the head edge of the bag The present invention relates to a brewing bag for tea, in particular, forming a knot by pulling. Furthermore, the present invention provides a decoction bag, especially for tea, which has its head closed by a folded corner and a central portion folded thereafter, preferably using the two needles. It relates to a method of closing with a thread labeled at the end.
[0002]
[Prior art]
It is known to close decoction bags exclusively with a single thread. For this purpose, the corners are first folded at the head of the decoction bag, and then the central part is folded over these folded corners to ensure that the decoction bag is closed. This closure is ensured by a single thread, but there are several possibilities for the thread attachment.
[0003]
In the known technique described in German Utility Model Registration No. 29613448, the thread placed on the head of the decoction bag is sewn using another fixing thread. When the yarn end portion is combined with the decoction bag by this method, it cannot withstand a relatively high load, which is technically expensive.
[0004]
In order to provide a simpler thread connection, in EP 0 807 579, there are two holes in the folded head and a decoction bag is placed next to the tensioned thread, which thread is at the height of the hole. And a grasping needle that accepts the thread and passes both ends of the thread through the hole is allowed to pass through each hole. The free end of the thread that penetrates the hole in the brew bag is secured to the label, for example by welding or sewing. The disadvantage is that it is loosely fixed and therefore unstable, which can open the folded area of the head, resulting in the contents of the decoction bag falling off and the loss of aroma and freshness. There is a risk of breaking.
[0005]
Furthermore, in the thread closure disclosed in EP 0 69 1 268, the needle penetrates the only hole in the head of the decoction bag, this needle catches the thread located behind it and passes the loop through the hole. And then use this loop to form the knot. In this case, the disadvantage is that the folded corner of the head and the center folded over are grasped by each other, and also by the bag and thread coupling, and are joined by the formed knot. It is not. In this case, even if folding, drilling and thread guiding are performed with high manufacturing accuracy, the closure is not sufficiently reliable.
[0006]
[Problems to be solved by the invention]
The object of the present invention is to ensure that the folded portions of the decoction bag are securely fixed to each other and also to the bag by means of a thread connection that is low in technical cost and can be easily made at high production speeds.
[0007]
[Means for Solving the Problems]
In order to solve this problem, in the present invention, two holes are formed in the head at the left and right of the longitudinal axis of the bag and spaced apart from each other. A loop is formed through the folded corner and center, and one end of the thread is passed through the first hole and the other end is passed through the second hole to form a loop. It was placed on the head edge of the thread, and both ends of the thread were passed through the loop from below to form a doubly fixed knot. In this case, it is preferably formed by thread portions that intersect with each other and overlap each other, and a short thread end and a long thread end can be provided. Especially long thread ends are used to fix labels. In a preferred embodiment, in order to increase the stability of the knot, the short yarn ends are arranged in contact with the bag wall under the long yarn ends in the yarn portion where the rings intersect and overlap each other. According to the present invention, the bent corner portion and the central portion folded on the corner portion can be reliably fixed to each other and also to the bag. In this case, a simplified manufacturing is also provided by the fact that conventional bags are relatively thick and therefore do not have to penetrate or perforate longitudinal seams which are difficult to process. The knot connection itself cannot be doubled by providing two spaced holes and passing the yarn ends separately. Therefore, even if one yarn end is unwound from the loop, the knot is reliably maintained by the additional winding formed by the second yarn end.
[0008]
By improving the known method described at the outset, the solution according to the method of the present invention is such that the free end of the thread spans the recess of the holder and the head of the decoction bag is placed in the holder. In this case, the thread loop is placed around the head edge of the decoction bag, and then the head 2 passing through the folded end of the free end of the thread and the continuous long part. Through the two holes, the free end and the continuous part are first passed through the loop, then withdrawn completely from the decoction bag, and finally the continuous part is pulled to tighten the winding of the yarn. Preferably, two needles that penetrate the decoction bag under the closed part of the loop are used to catch the yarn, and the holder can have a guide opening for these needles. In order to thread the thread, the thread must be cut at successive points before the needle is pulled back at the latest. In this way, the continuous portion forms a long yarn end and can be used for label fixing.
[0009]
The method according to the invention closes the folded head of the decoction bag with only one thread and does not use any auxiliary thread. The thread is pierced or pierced by the needle through the head of the decoction bag. In this case, the holder has a guide opening for the needle. Since these needles only perform a simple movement to pierce the head of the decoction bag, a simple and rapid movement process is possible. It is not necessary to make a hole in the head of the decoction bag in advance. The bag head is securely closed by penetrating the thread to the left and right of the center, and the folded corner is also fixed. Due to the continuous operation method, the fixing can be carried out in a high number in a quiet machine operation. The knot cannot be broken based on the frictional force even under slight original stress, that is, loosely tightened.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the decoction bag 1 shown in FIGS. 1A to 1C, the corners 1a and 1b are first folded at the head 6 according to FIG. 1C, and then the central portion 1c is folded thereon. close. Then, the substances present inside the room, especially tea, will not go out. Next, as shown in FIGS. 2 (a) to 9 (b), a thread closure 7 is provided in the decoction bag 1. The structure can be clearly seen particularly in FIG. In order to form the thread closure 7, the head 6 is formed with two holes 8, 9 which are spaced laterally from each other on the left and right of the longitudinal axis of the bag. The corner portion 1a or 1b and the central portion 1c are penetrated. In order to make this possible, as shown in FIG. 1C, a total of four holes are provided in the head 6 of the decoction bag 1 with the central portion 1c not yet folded. These holes, after folding the central portion 1c, form holes 8 and 9 that coincide with each other and pass through coaxially.
[0011]
Furthermore, the thread closure 7 has a thread 3. One end 3b of the yarn 3 is passed through the first hole 9 and the other end 3c is passed through the second hole 8 so as to form a ring 3a. The wheel 3a is on the front side of the bag 1 in the drawing, and the corners 3b and 3c are on the rear side of the bag 1 in the drawing. The ring is placed on the head edge 10 of the decoction bag 1, and both ends 3b and 3c of the thread 3 are passed through the ring 3a from below. Pulling one or both ends of the thread forms a doubly fixed knot 11. This knot 11 fixes the corners 1a and 1b and the central part 1c of the head 6 to each other in the closed position and also to the decoction edge.
[0012]
Further, as can be seen in the drawings, the short yarn end 3b is formed below the long yarn end 3c in the yarn portion that is overlapped with the ring 3a. It is placed in contact with the bag wall.
[0013]
In order to form the above-mentioned closure, as shown in FIGS. 2 (a) and 2 (b), the closed head 6 of the decoction bag 1 is inserted into the recess 2 a of the holder 2. Before that, the thread 3 in the shape of a ring 3a has been passed over the recess 2a of the holder 2, which is best seen in FIG. In this case, the free end 3 b of the ring 3 a rests on one side of the recess 2 a together with the continuous part 3 c of the thread 3, and the closed part of the ring 3 a rests on the other side of the recess 2 a of the holder 2. .
[0014]
As best seen from FIG. 2 (a), the wheel 3a is pushed into the recess 2a by the head edge of the decoction bag 1, so that it is placed around the head edge.
As shown in FIGS. 3 (a) and 3 (b), the two needles 4 shown in the starting position in FIGS. 2 (a) and 2 (b) are below the wheel 3a and the head of the decoction bag. Pierce. These needles 4 are, as shown in FIGS. 3 (a) and 3 (b), a ridge 4a (see FIG. 2 (a)) formed on the lower side, on the one hand, the free end of the thread 3 The part 3b is grasped, and on the other hand, the continuous part 3c of the yarn 3 is grasped.
[0015]
Here, when the needles 4 are pulled back to the starting position according to FIGS. 4 (a) and 4 (b), these needles 4 are on the one hand free ends of the thread 3, as shown in FIGS. 4 (a) and 4 (b). The part 3b is entrained, and on the other hand, the continuous part 3c of the yarn 3 is entrained. While the free end 3b is completely pulled out from the head of the decoction bag 1, a ring 3d positioned below the center of the ring 3a is formed in the continuous part 3c of the thread by pulling back the corresponding needle 4. It is formed. This state is clearly shown in FIG.
[0016]
Now, in order to achieve the complete winding of the head of the decoction bag 1 by the end of the yarn 3, as shown in FIGS. 5 (a) and 5 (b), the continuous portion 3c, i.e. the length of the yarn 3 is long. It is necessary to completely pull the yarn end from the decoction bag 1. This is performed, for example, by continuous conveyance of the decoction bag 1, and the remaining part of the continuous part 3c of the yarn 3 is completely passed through the ring 3a. Finally, by applying a specified tensile force to the continuous portion 3c of the yarn 3, the winding is tightened, and the states shown in FIGS. 5 (a) and 5 (b) occur.
[0017]
In order to fix the label 5 shown in FIGS. 6 (a) to 9 (b) to the other end of the yarn 3, as shown in FIGS. 6 (a) and 6 (b), the end of the yarn 3 Place part 3e on one side of label 5. Preferably, the label 5 is pierced by using a needle with a hook portion again, and the end portion 3e of the thread 3 is grasped.
